8: Status of Syntax WD No progress. Dave Beckett hopes to have something by end of next week.

9: Issue: rdfs-transitive-subSubProperty Propose Approve test case

Not considered since no-one has reviewed test cases. ACTION 2001-11-30#1 Dan Connolly: Review rdfs-transitive-subSubProperty test cases. ACTION 2001-11-30#2 Pat Hayes: Review rdfs-transitive-subSubProperty test cases.

10: Manifest Proposal Review Jans proposal.

Jos wants a distinction between rdfs and rdf entailment. Brian notes that this text belongs in the Test Cases WD. DECISION 2001-11-30#2 Jan Grant will co-edit the Test Cases WD. ACTION 2001-11-30#3 Jan Grant: Get access to test case areas of W3C site.

12: Issue #rdfms-rdf-names-use [[[ Propose the WG

o Resolves that the use of rdf:RDF, rdf:ID, rdf:about, rdf:resource, rdf:bagID, rdf:parseType, rdf:aboutEach and rdf:li except as reserved names as specified in the grammar is an error. o resolves that test case http://www.w3.org/2000/10/rdf-tests/rdfcore/rdf-containers-syntax-vs-schema/test005.rdf be obsoleted o resolves that a copy of that test case be created as an error test case o actions DaveB to create test cases for the above cases o actions DaveB to identify any similar cases to those above and create test cases to cover them also ]]]

Jeremy Carroll asked for clarification that this still allows rdf:_NNN as a typed node. Dave Beckett indicated that it did.

Dan Connolly seconded proposal.

No objections to the proposal, no abstentions.

ACTION 2001-11-30#4 Dave Beckett: Create test cases covering reserved use of rdf names in this proposal. DECISION 2001-11-30#3 Reserve use of names in the rdf namespace as in agenda.

Para 196

Eric and Ron who were both in the first WG, clarified that the second URL in para 196 is not a typo; but was intended to reserve namespace for future use.

Jeremy Carroll seconded Dave Beckett's e-mail proposal that para 196 be dropped.

Discussion.

DECISION 2001-11-30#4 'Delete' para 196 from Syntax WD. [Scribe pedantic note: while the discussion was in terms of deleting this paragraph, since it is in a different document, it is more a question of not including it]. ACTION 2001-11-30#5 Dave Beckett: Create test case showing that the 2nd URL in Para 196 is permitted.

11: Datatypes Action 2001-11-16#9 FrankM

Continued. Action 2001-11-16#10 Jeremy WebOnt working group.

Done - but no meaningful response - too early in WOW-G process.

Action 2001-11-16#11 MikeD DAML+OIL joint committee.

Both Pat Hayes and Mike Dean reported back from the Joint Committee. Apparant summary: P preferred, then U, then S, which could be lived with.

ACTION 2001-11-30#6 Mike Dean: Sumamrise Joint Committee position, confirm with them, circulate to us.

Review Sergey's document and status of ongoing discussions.

Many positive comments on Sergey's document. General discussion: particularly about Perl datatyping, and its relationship to Jena and Squish datatyping. Brian observes that there is increasing support for something other than S.

ACTION 2001-11-30#7 Pat Hayes: Write up P for inclusion in Sergey's document. ACTION 2001-11-30#8 Dan Connolly: Write up Perl datatyping proposal as e-mail to group. ACTION 2001-11-30#9 Jeremy Carroll: Write up XML Schema structures datatyping proposal as e-mail to group.

The meeting ended as the bridge died.

13: Issue rdfms-aboutEach NOT REACHED

14: Issue: rdfms-assertion NOT REACHED

15: Semantics of Reification - what progress NOT REACHED

Brian: some have not implemented this at all some have assumed that it was a typo

Jeremy reminds group that DaveB proposed dropping this para seonds proposal

Dan wants to keep some record

Pat suggests footnote

Aaron points out this is the URI of M&S

Action DaveB to create test case showing this name is not special Decision drop para 196 no dissent

Dave points out no update of syntax doc is required.

+Sergey

  1. Datatypes

Action 11-16#9 continued 11-16#10 done - but no responses since too early 11-16#11 with DAML+OIL

Pat: indicates that Patel-Schneider believes that blank node proposals (incl S) violate current XML practice

The use of range specs is common and is a good thing. Brian indicates that this includes lexical mappings. PatH issues to do with union datatypes and lexical mappings

Can of worms.

P preferred, U could be accomodate, S could be lived with.

Action Mike to summarise joint committee position, confirm with them, get back to us

Sergey's doc

Dan: "great", Graham's stuff should be incorporated.

Dan gives overview of Perl typing.

Jena & Squish take this view.

PatH thinks of Perl as bcpl of thinking

stops using type info as a constraint.

patrick: appreciates Perl In perl using string comp is on lexical forms whereas int comp is on value leaves decision as to which space is left to operator

Graham: propogramming languages stuff maybe misleading

DanC: Perl documentation says there is one type "scalar"

DanC reiterates e-mail about entailment

Brian proposes we include something about P proposal

Action Pat to write P proposal in .

DanC will write up Perl approach DaveB and FrankB interested

Jjc will write up

Meeting cut off.
